Abstract

The burner (1) has a nozzle pipe (7) and a fuel fluid inlet pipe (9), which are in connection with the nozzle pipe for feeding the fuel fluid into the nozzle pipe, is proposed. The nozzle pipe has a nozzle discharge opening (15) and is designed for spraying a stream of fuel fluid or a mixture of air and fuel fluid into a combustion chamber (3) and further comprises in the region of the nozzle discharge opening protruding elements (19) towards the center of the opening. The elements are formed by a nozzle tube section extending to nozzle discharge opening with inner circumferential surfaces.
